Hi Reginold,

When from APNS the message comes first who have a chance to modify it is Service Extension, the next in chain is Content Extension.

Let’s assume all the certificates are correctly setup.

Then next what is needed that the Content Extension Info.plist have correctly setup the “UNNotificationExtensionCategory” e.g. “krco_category”

then in Push Notification you need under “aps” the field with “category”: “krco_category”. If these two matches, then in case you add break point in Content Extension it should stop and that is the PoC that setup is done right.

But it is hard to debug without context. This is based on my assumption what could be the pain points.

Hope this helps in debugging.
